ICAO Standard Phraseology a Quick Reference Guide for Commercial ICAO Standard Phraseology A Quick Reference Guide for Commercial Air Transport Pilots Communication error is the biggest causal factor in both level busts and runway incursions in Europe. This document aims to provide Commercial Air Transport (CAT) pilots and other pilots flying IFR within controlled airspace with a quick reference guide to commonly used radiotelephony (RTF) phrases that may be encountered during a routine CAT flight in European Airspace. ICAO Phraseology Reference Guide ALL CLEAR AGC safety initiative Introduction Communication error is the biggest causal factor in both level busts and runway incursions in Europe. This document aims to provide Commercial Air Transport (CAT) pilots and other pilots flying IFR within controlled airspace with a quick reference guide to commonly used radiotelephony (RTF) phrases that may be encountered during a routine CAT flight in European Airspace. It also explains some of the rationale behind the use of certain words and phrases to aid understanding and reinforce the need for compliance with standard phraseology. The goal is to improve safety by raising RTF standards. The need for clear and unambiguous communication between pilots and Air Traffic Control (ATC) is vital in assisting the safe and expeditious operation of aircraft. It is important, therefore, that due regard is given to the use of standard words and phrases and that all involved ensure that they maintain the highest professional standards when using RTF. This is especially important when operating within busy sectors with congested frequencies where any time wasted with verbosity and non-standard, ambiguous phrases could lead to flight safety incidents. Phraseology has evolved over time and has been carefully developed to provide maximum clarity and brevity in communications while ensuring that phrases are unambiguous. However, while standard phraseology is available to cover most routine situations, not every conceivable scenario will be catered for and RTF users should be prepared to use plain language when necessary following the principle of keeping phrases clear and concise. ICAO Phraseology Reference Guide 2 ALL CLEAR AGC safety initiative Contents 1. Clearance and Taxi 2. Take-off and Departure 3. Read-back 4. Climb, Cruise and Descent 5. Approach and Landing 6. Emergency Communications Note: This document uses RTF examples showing both pilot (denoted by blue italic text) and ATCO (denoted by grey text) communication. For example: Pilot - Metro Ground, Big Jet 345, request taxi ATC - Big Jet 345, Metro Ground, taxi to holding point A1, hold short of Runway 18 ICAO Phraseology Reference Guide 3 ALL CLEAR AGC safety initiative CLEARANCE AND TAXI ICAO Phraseology Reference Guide 4 ALL CLEAR AGC safety initiative Taxiing - A Safety Critical Activity RTF is crucial to the safety of the flight during taxiing. Any mistake that causes the aircraft to enter a runway in error could be catastrophic. Taxi Clearance Limit All taxi clearances will contain a clearance limit, which is the point at which the aircraft must stop unless further permission to proceed is given. Noting Down Taxi Clearances Complex or lengthy taxi clearances should be noted down by crews. RTF Taxi Instructions to Departure Runway Metro Ground, Big Jet 345, request taxi Big Jet 345, Metro Ground, taxi to holding point C, runway 27 Taxi to holding point C, runway 27, Big Jet 345 Big Jet 345, contact Metro Tower 119.2 Contact Metro Tower 119.2, Big Jet 345 Crossing an Intermediate Runway If a taxi route involves crossing a runway, whether active or not, specific clearance to cross that runway is required. Departure Delay Information Departure sequence information such as ‘number 5 to depart’ or ‘expect departure in …’ is NOT a take-off clearance. RTF Taxiing Across an Intermediate Runway Metro Ground, Big Jet 345, request taxi Big Jet 345, Metro Ground, taxi to holding point A1 runway 18 Taxi to holding point A1 runway 18, Big Jet 345 When traffic permits Big Jet 345 cross runway 18 at A1, taxi to holding point C, runway 27 Cross runway 18 at A1, taxi to holding point C, runway 27, Big Jet 345 ICAO Phraseology Reference Guide 5 ALL CLEAR AGC safety initiative NB: ATC may request Big Jet to confirm when Runway 18 is vacated A Conditional Taxi Clearance Conditional clearances may expedite traffic flow, but there are risks. Read-back must be in full and in the same sequence as given. A taxi clearance, shown below, allows taxi after another action has first taken place ie. the condition of the clearance. Where there may be ambiguity as to the subject of the condition, additional details such as livery and/or colour are given to aid identification. A conditional taxi clearance allows the aircraft to taxi only after another action has taken place. The structure and order of conditional clearances is essential to their safe execution. Correct read-back of a conditional clearance is vital. Metro Delivery, Big Jet 345, Stand Bravo 1, Boeing 737 with information Q, QNH1006, request clearance Big Jet 345, Metro Delivery, Cleared to Smallville, T1A departure, Squawk 3456, slot time 1905 Cleared to Smallville, T1A, Squawk 3456, Big Jet 345 Big Jet 345, request start up Big Jet 345, start up approved, contact Metro Ground 118.750 for taxi instructions Start up approved, contact Metro Ground 118.750 for taxi instructions, Big Jet 345 Metro Ground, Big Jet 345 Stand B1, request taxi Big Jet 345, Metro Ground, after the red and white Antonov with the purple fin, taxi to holding point runway 08 After the red and white Antonov with the purple fin, taxi to holding point runway 08, Big Jet 345 ICAO Phraseology Reference Guide 6 ALL CLEAR AGC safety initiative *ICAO: In all cases a conditional clearance shall be given in the following order and consist of: 1. Identification; 2. The condition 3. The clearance; and 4. Brief reiteration of the condition Conditional clearance to cross the intermediate runway: Conditional phrases, such as “behind landing aircraft” or “after departing aircraft”, shall not be used for movements affecting the active runway(s), except when the aircraft or vehicles concerned are seen by the appropriate controller and pilot. The aircraft or vehicle causing the condition in the clearance issued shall be the first aircraft/vehicle to pass in front of the other aircraft concerned. NB: Beware - the ICAO phrase ‘behind’ has been misinterpreted as an instruction to ‘get close to’ the preceding aircraft, leading to serious jet blast incidents. Big Jet 345, after landing Airbus 321, cross Runway 09 at C2, after After landing Airbus 321, cross Runway 09 at C2 after, Big Jet 345 Then: Big Jet 345, taxi to holding point C1, runway 27 Taxi to holding point C1, runway 27, Big Jet 345 Then: Big Jet 345, contact Metro Tower 123.625 Contact Metro Tower 123.625, Big Jet 345 ICAO Phraseology Reference Guide 7 ALL CLEAR AGC safety initiative TAKE OFF AND DEPARTURE ‘Take-off’ shall only be used when issuing a clearance to take-off. § Do not use phrases such as ‘prior to take-off’ or ‘after take-off’. § If the controller uses ‘after departure’ or ‘follow’, this is NOT a clearance to take-off. Any instructions to HOLD, HOLD POSITION or HOLD SHORT OF, shall be read back in full using the appropriate phrase – HOLDING or HOLD SHORT OF. In the airport environment, the word ‘cleared’ shall only be used in connection with a clearance to take-off or land. To aid clarity, a take-off clearance will always be issued separately. RTF Take-off Clearance Metro Tower, Big Jet 345, approaching holding point C1 Big Jet 345, Metro Tower, line up runway 27 Lining up runway 27, Big Jet 345 Big Jet 345, runway 27, cleared for take-off Cleared for take-off, Big Jet 345 Once airborne: Big Jet 345, contact Metro Radar 124.6 Contact Metro Radar on 124.6, Big Jet 345 Amendment to Departure Clearance Amendments to departure clearances are known to contribute to runway incursion incidents. The phraseology for amendments to departure clearances where the aircraft is approaching the runway will begin with ‘hold position’. ICAO Phraseology Reference Guide 8 ALL CLEAR AGC safety initiative RTF Amendment to Departure Clearance Metro Tower, Big Jet 345, approaching holding point C1 Big Jet 345, Metro Tower, hold at C1 Hold at C1, Big Jet 345 Big Jet 345, hold position, amendment to clearance, T3F departure, climb to 6000 feet Holding, T3F departure, climb to 6000 feet, Big Jet 345 Or: Big Jet 345 hold position, after departure climb to altitude 6000 feet Holding, after departure climb to 6000 feet, Big Jet 345 Conditional Line-Up Clearance Important points involving the active runway: § The condition is always given directly after the call-sign and before the clearance. § Conditional clearances must be read back in full and in exactly the same sequence as given plus a brief reiteration of the condition. § The aircraft or vehicle that is the subject of the condition must be visible to the flight crew and the controller. § The subject aircraft or vehicle of the condition shall be the next aircraft/vehicle to pass. § The condition must relate to only one movement. § Always clarify if unsure. RTF A Conditional Line Up Clearance Metro Tower, Big Jet 345, approaching holding point C1 Big Jet 345, Metro Tower, hold at C1 Hold at C1, Big Jet 345 Conditional line up clearance: Big Jet 345, behind landing Boeing 757, line up runway 27, behind Behind landing Boeing 757, line up runway 27, behind, Big Jet 345 ICAO Phraseology Reference Guide 9 ALL CLEAR AGC safety initiative Cancelling Take-off Clearance If take-off clearance has to be cancelled before the take-off roll has commenced, the flight crew shall be instructed to hold position, stating reason.

  • Mandatory Call Sign Lesson Get Ready for STARBASE in 10 Steps!
    Get Ready for STARBASE – Mandatory Call Sign Lesson Overview During this lesson, students will gain a brief introduction to STARBASE. STARBASE goals and expectations will be reviewed with students. Students will then brainstorm ideas for a call sign that will uniquely identify them during their five days at STARBASE Minnesota Duluth. Pilots and astronauts have call signs to signify themselves as unique individuals and to build team comradery. Call signs are used at STARBASE to allow students (and adults) to creatively express their personalities, build a sense of community, and see themselves in a new light. For example, “Allison” might feel that she is not “good at math” but “Galaxy” might see herself as a future Mars rover programmer. Objectives Students will be able to: - Brainstorm a variety of possible call sign names through guided personal research - Choose a call sign using their research and create a personalized nametag - Recall STARBASE goals, expectations, and consequences through guided class discussion - Identify how they will work as a team at STARBASE through a guided activity Materials - One reusable or five temporary name tags per student (ex. mailing labels) - Markers - List of categories students can use to brainstorm call signs (see attached) - Class registration list to record call signs Get ready for STARBASE in 10 steps! (25 minutes) Introduction 1. Explain the STARBASE program to students: “At STARBASE you will have the opportunity to experience science, technology, engineering, and math (STEM) through a variety of experiments and challenges! Some activities include: coding robots, conducting chemistry experiments, solving engineering challenges, using CAD software to design you own creation, using innovative technology like virtual reality (VR) and 3D printing.

    THE DIFFERENCE BETWEEN HIGHER AND LOWER FLAP SETTING CONFIGURATIONS MAY SEEM SMALL, BUT AT TODAY'S FUEL PRICES THE SAVINGS CAN BE SUBSTANTIAL. 24 AERO QUARTERLY QTR_04 | 08 Fuel Conservation Strategies: Takeoff and Climb By William Roberson, Senior Safety Pilot, Flight Operations; and James A. Johns, Flight Operations Engineer, Flight Operations Engineering This article is the third in a series exploring fuel conservation strategies. Every takeoff is an opportunity to save fuel. If each takeoff and climb is performed efficiently, an airline can realize significant savings over time. But what constitutes an efficient takeoff? How should a climb be executed for maximum fuel savings? The most efficient flights actually begin long before the airplane is cleared for takeoff.

  • TCAS II) by Personnel Involved in the Implementation and Operation of TCAS II
    Preface This booklet provides the background for a better understanding of the Traffic Alert and Collision Avoidance System (TCAS II) by personnel involved in the implementation and operation of TCAS II. This booklet is an update of the TCAS II Version 7.0 manual published in 2000 by the Federal Aviation Administration (FAA). It describes changes to the CAS logic introduced by Version 7.1 and updates the information on requirements for use of TCAS II and operational experience. Version 7.1 logic changes will improve TCAS Resolution Advisory (RA) sense reversal logic in vertical chase situations. In addition all “Adjust Vertical Speed, Adjust” RAs are converted to “Level-Off, Level-Off” RAs to make it more clear that a reduction in vertical rate is required. The Minimum Operational Performance Standards (MOPS) for TCAS II Version 7.1 were approved in June 2008 and Version 7.1 units are expected to be operating by 2010-2011. Version 6.04a and 7.0 units are also expected to continue operating for the foreseeable future where authorized. 2 Preface................................................................................................................................. 2 The TCAS Solution............................................................................................................. 5 Early Collision Avoidance Systems................................................................................ 5 TCAS II Development .................................................................................................... 6 Initial

  • Advisory Circular (AC)
    U.S. Department Advisory of Transportation Federal Aviation Administration Circular Subject: Parts 91, 121, 125, and 135 Date: 7/30/12 AC No: 120-74B Flightcrew Procedures During Taxi Initiated by: Change: Operations AFS-200/800 1. PURPOSE. This advisory circular (AC) provides guidelines for the development and implementation of standard operating procedures (SOP) for conducting safe aircraft operations during taxiing to avoid causing a runway incursion. In accordance with Federal Aviation Administration (FAA) Order 7050.1, Runway Safety Program, the definition of a runway incursion is any occurrence at an aerodrome involving the incorrect presence of an aircraft, vehicle, or person on the protected area of a surface designated for the landing and takeoff of aircraft. It is intended for use by persons operating aircraft with two or more pilots on the flight deck under Title 14 of the Code of Federal Regulations (14 CFR) parts 91, 121, 125, and 135. The FAA recommends that these guidelines become an integral part of all SOPs, flight operations manuals (FOM), and formal flightcrew member training programs. The use of flightcrew SOPs should be emphasized and employed during all phases of flight, including ground operations. Appendices 1 and 2 of this AC contain examples of SOPs that are identical or similar to some SOPs currently in use. These appendices are not directive or prescriptive in nature and do not represent a rigid FAA view of Best Practices. SOPs may vary among fleets and among certificate holders and may change over time. Operators may integrate the information contained in Appendices 1 and 2 into their fleet-specific, route-specific, and equipment-specific operations and checklists.
